A 2.2 kg block is pushed 1.36 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of 68.4 degrees with the horizontal . The acceleration of gravity is 9.8 m/s squred . If the coefficient of kinetic friction between the block and the wall is 0.511 , find the work done by F . Answer in units of J .
